Abstract
Methods and systems for processing waste materials and for manufacturing composite materials are disclosed herein. According to some embodiments, the heterogeneous waste includes a plastic component and a non-plastic component, and the non-plastic component includes a plurality of pieces of waste. The heterogeneous waste is heated to melt at least a portion of said plastic component and reducing a volume of said heterogeneous waste, and then mixed (e.g. by rotating a mixing chamber or by stirring) until at least some said pieces are each encapsulated by the melted plastic component. Upon cooling, the mixture optionally sets into a composite material. The presently disclosed invention does not require pre-sorting of the heterogeneous waste and is operative to process "as is" waste. Optionally, the waste is pre-sorted.
Exemplary uses for the composite material include but are not limited to flooring sheets, construction bricks, thermal insulation, acoustic walls, road paving materials, road beds, ballistic shields shock absorbing flooring, artificial islands, artificial reefs, and marine docks.
Exemplary uses for the composite material include but are not limited to flooring sheets, construction bricks, thermal insulation, acoustic walls, road paving materials, road beds, ballistic shields shock absorbing flooring, artificial islands, artificial reefs, and marine docks.
